A doctor said on Tuesday that they are investigating whether the drug commonly known as bath salts played a role in the face-eating attack in Miami over the weekend. The attacker has been identified as Rudy Eugene, 31, and according to court filings, he had no income and his assets included $2 cash and a $50 cellphone. Eugene was shot and killed by a police officer after he was apparently caught, naked, trying to eat the face of another naked man on a busy Miami highway. The victim is recovering in the hospital, most of his skin gone, his eyes gouged and his nose bitten. Police originally theorized that “cocaine psychosis” could have played a role in the attack, but an emergency room doctor said the attack could have been caused by bath salts, an LSD-like drug popular in the South, especially Florida.
